You might be referring to Cerro Colorado, which is located within the Ngöbe-Buglé comarca in western Panama, where a group of consultants have been working for a company called Corriente Resources. It's unclear if that's the company they've continued to work for, because it was bought up by a Chinese consortium that bought their holdings in Ecuador a number of years ago.
It has been working on promoting mining in that area, where the pushback on that and the massive protests in the last couple of years have actually led to a prohibition on mining in the area of Cerro Colorado currently.
